From 95e960cece76cb538fcac03ac80893db0f1e6a15 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 10 Dec 2012 17:27:57 +0100 Subject: [PATCH] ALSA: hda/realtek - Make path->idx[] and path->multi[] consistent So far, idx[i] and multi[i] indicate the attribute of the widget path[i - 1]. This was just for simplifying the code in __parse_output_path(), but this is rather confusing for later use. It's more natural if both idx[i] and multi[i] point to the same widget of path[i]. This patch changes to that way.
